Description

Technical Field

[0001] The present invention relates to the technical field of batch processing of fruits and vegetables, and more particularly to an irradiation-based batch processing device for fruits and vegetables and a method for using the same. Background Art

[0002] As consumers demand higher quality and safety for fruits and vegetables, irradiation technology, as a non-thermal sterilization method, plays a vital role in post-harvest processing of fruits and vegetables. High-energy electron beam irradiation sterilizes by disrupting microbial DNA while inhibiting enzyme activity to slow spoilage. It is particularly suitable for batch processing. Traditional batch irradiation systems typically use a linear conveyor belt combined with an overhead electron accelerator. Fruits and vegetables move unidirectionally along the belt, while an overhead irradiation source emits an electron beam vertically downward, covering the surface. These systems achieve continuous processing by matching the belt speed with the electron beam scanning frequency.

[0003] However, as production capacity demands increase, the contradiction between irradiation efficiency and uniformity becomes increasingly prominent. While existing technologies can achieve basic coverage through unidirectional irradiation from top to bottom, in actual batch processing, stacked fruits and vegetables or irregularly shaped surfaces can easily create scanning blind spots and irradiation dead angles. This is especially true when the fruit and vegetable layers are unevenly thick or closely arranged, limiting the penetration depth of the electron beam at the top and potentially leading to insufficient irradiation dose at the bottom due to energy attenuation. Some solutions have attempted to use multi-angle reflectors or add lateral auxiliary irradiation sources, but due to the linear propagation characteristics of the electron beam, reflectors are prone to energy loss, and multi-source layouts significantly increase equipment complexity and cost.

[0004] Specifically, the core defect of the existing irradiation-based batch fruit and vegetable processing equipment stems from the inherent limitations of its geometric layout. The top-down irradiation path of the configured electron beam is perpendicular to the track plane, which makes it difficult to effectively cover the sides and bottoms of fruits and vegetables, and cannot be adapted to high-speed assembly lines.

[0018] A method for using an irradiation-based batch fruit and vegetable processing device comprises the following steps:

[0019] S1: First, the conveyor belt is started to transport the fruits and vegetables into the irradiation area. The electron accelerator injects the electron beam into the vacuum cavity of the annular irradiation chamber. The electrically controlled magnetic block deflects the electron beam along the annular path through the magnetic field, and the fruits and vegetables are irradiated 360 degrees through the annular titanium window.

[0020] S2: Then, the servo motor is started to drive the gear plate to drive the gear ring to rotate, so that the ring clamp of the linked ring module rotates around the ring irradiation cavity. The ring clamp absorbs the magnetic coating of the double-sided scraping module through the metal coating, driving it to slide along the embedded groove and simultaneously clean the ring titanium window and the end face of the magnetic block;

[0021] S3: Then, when the annular chuck rotates, the annular disc of the U-shaped plate is squeezed by the toothed ring, pushing the U-shaped squeezing plate to compress and reset the airbag sleeve. The airbag contracts and absorbs the mixed reagent from the storage tank through the drainage tube. When it expands, it is transported to the spray plate through the delivery tube to soak the cleaning sponge. The liquid drainage wire absorbs the deionized water in the cavity of the partition plate for secondary purification of the sponge.

[0022] S4: Finally, the electrically controlled fan starts, sending airflow to the exhaust slot to sweep away the residue on the surface of the circular titanium window, and at the same time introduces the friction heat into the first cavity shell through the reserved opening. After the wind accelerates the drying of the cleaning sponge, the spray valve is closed and the irradiation operation is resumed.

[0023] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0024] (1) This solution solves the uniformity defect of the traditional vertical irradiation layout through the coordinated design of the annular irradiation chamber and the electric-controlled magnetic block. The annular irradiation chamber is set on one side of the conveyor belt. Combined with the magnetic field control of the circular electric-controlled magnetic block, the electron beam is dynamically deflected along the annular path in the vacuum chamber to achieve 360-degree irradiation coverage without dead angles. Compared with the blind spot problem on the sides and bottom of fruits and vegetables caused by the top unidirectional irradiation in the existing technology, it replaces the mechanical rotating structure with the magnetic field superposition, and matches the conveying speed in real time in the high-speed assembly line, which can effectively improve the uniformity of the irradiation dose. The curvature of the annular titanium window matches the electron beam path, reducing the energy scattering of non-vertical incidence, avoiding the energy loss of the traditional reflector caused by the air environment, and ensuring the sterilization efficiency and penetration depth.

[0025] (2) Through the integrated design of the double-sided scraping module and the linkage ring module, intelligent maintenance of synchronous cleaning inside and outside the vacuum chamber is realized. During the operation, the pollutants on the surface of the ring titanium window and the end face of the magnetic block can be efficiently scraped respectively, solving the problem of rapid wear and easy electrostatic interference of traditional single coatings. The linkage ring module drives the scraping structure to rotate synchronously through the servo motor to drive the gear ring, completing real-time cleaning during the irradiation process without stopping the operation. Through the adsorption linkage of the magnetic coating and the metal coating, the dynamic fit of the scraping trajectory and the irradiation chamber structure is ensured, effectively eliminating the interference of metal debris and fruit and vegetable residues in the vacuum chamber on the electron beam path, and ensuring the long-term operation stability of the device.

[0026] (3) The linkage mechanism between the cleaning module and the liquid storage module realizes the online cleaning and maintenance of the irradiation window. The liquid storage module automatically absorbs the mixed reagent by rotating and squeezing the toothed ring through the cooperation of the reset airbag and the trigger structure. The cleaning cotton is soaked by capillary liquid and atomized spray to complete the decontamination and secondary purification of the surface of the ring titanium window. The temperature-controlled airflow of the electric fan simultaneously reduces friction heat and accelerates drying, forming a closed-loop process from cleaning to purification and then to drying. Compared with the traditional manual cleaning method of shutdown, maintenance can be completed during continuous irradiation operation, avoiding production interruption and significantly improving the consistency of batch processing and equipment reliability.

[0046] The following describes in detail, with reference to the accompanying drawings and specific examples, a batch irradiation-based fruit and vegetable processing device and its method of use provided by the present invention. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known techniques. Furthermore, the accompanying drawings are provided solely for the purpose of illustrating the embodiments in greater detail and are not intended to limit the present invention.

[0047] like Figures 1 to 9 As shown, an embodiment of the present invention provides a batch fruit and vegetable processing device based on irradiation, comprising an assembly frame 1, a conveyor belt 2 is configured on the assembly frame 1, and a gantry 3 is fixedly installed at a position outside the conveyor belt 2, an electron accelerator 4 is fixedly installed on the gantry 3, and an annular irradiation chamber 5 is configured at the output end of the electron accelerator 4. The annular irradiation chamber 5 is sleeved on the outer side of the conveyor belt 2 for conveying fruits and vegetables;

[0048] The interior of the annular irradiation chamber 5 is a vacuum cavity structure. The electron beam accelerating tube of the electron accelerator 4 is connected to the top of the annular irradiation chamber 5 and is used to inject an electron beam into the cavity of the annular irradiation chamber 5. A plurality of electrically controlled magnetic blocks 6 are fixedly installed in a circular pattern on the outer edge of the annular irradiation chamber 5. The magnetic ends of the electrically controlled magnetic blocks 6 are all facing the center of the annular irradiation chamber 5. A circular titanium window 12 is sealed on the inner side of the annular ring of the annular irradiation chamber 5.

[0049] Among them, embedded grooves 10 are fixedly installed on the side walls on both sides of the inner cavity of the annular irradiation chamber 5. The embedded grooves 10 as a whole protrude toward the outer wall end of the annular irradiation chamber 5, and a double-sided scraping module 13 for real-time cleaning of the magnetic end of the electric-controlled magnetic block 6 and the annular titanium window 12 is movably configured through the embedded grooves 10, which is used to eliminate interference in the vacuum cavity while irradiating batches of fruits and vegetables.

[0050] In order to solve the problem of blind spots on the sides and bottom of fruits and vegetables caused by the vertical irradiation layout on the top in the existing technology, and the problem of being unable to achieve uniform coverage and efficient sterilization of batch processing in a high-speed assembly line environment, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution is mainly composed of an assembly frame 1, a conveyor belt 2, a gantry 3, an electron accelerator 4, a circular irradiation chamber 5, an electrically controlled magnetic suction block 6, an embedded groove 10, a circular titanium window 12, and a double-sided scraping module 13. The configured assembly frame 1 is a frame structure, which undertakes the load-bearing and space integration tasks of the entire device. The conveyor belt 2 and the gantry 3 are fixed on it, and the boundary isolation of the irradiation module and the conveying system is ensured through reasonable layout. The configured conveyor belt 2 is a flat-top chain plate conveying structure, the surface of which can be divided into an irradiation area and a non-irradiation area. The conveyor belt can be adjusted according to the size of fruits and vegetables to ensure that the position of fruits and vegetables is relatively fixed when passing through the irradiation chamber. The electron accelerator 4 is a high-frequency and high-voltage electric field driven accelerator. Its electron beam acceleration tube is connected to the top interface of the annular irradiation chamber 5 through a vacuum sealing flange to ensure that the electron beam is stably injected into the annular cavity. During operation, the magnetic field parameters are adjusted to control the deflection path and diffusion range of the electron beam in the annular cavity. The annular irradiation chamber 5 is integrally sleeved on one side of the conveyor belt 2. The configured electric-controlled magnetic block 6 is fixedly installed in a circular manner on the outer edge of the annular irradiation chamber 5. The electric-controlled magnetic block 6 limits the electron beam to the annular path of the annular irradiation chamber 5 through the deflection of the magnetic field. Because the electron beam is affected by the Lorentz force in the magnetic field, the direction of movement will be deflected. The charge of the electron beam is negative, so the deflection direction is perpendicular to the direction of the magnetic field, forming a circular motion. Trajectory, the electrically controlled magnetic blocks 6 are arranged in a circle along the outer edge of the annular irradiation cavity 5, and the magnetic pole direction of each magnetic block is perpendicular to the plane of the annular ring, that is, the direction of the magnetic field points radially to the center of the circle. The current intensity of the magnetic block is adjusted by the electronic control program to control the magnetic field intensity, and then the deflection radius of the electron beam is adjusted. After the electron beam is injected from the top, it performs uniform circular motion along the annular cavity wall under the action of the magnetic field to achieve 360-degree coverage without dead angles. In the actual working process, according to the fruit and vegetable conveying speed and irradiation dose requirements, the current parameters of the electrically controlled magnetic block 6 are adjusted by the controller to change the magnetic field intensity, thereby dynamically adjusting the deflection radius and energy distribution range of the electron beam to ensure the uniformity of the irradiation dose. The configured annular titanium window 12 is a titanium window structure in the shape of an annulus, and its annular curvature matches the deflection radius of the electron beam to ensure that the electron beam penetrates the annular titanium window 12 at a vertical or near-vertical angle, reducing energy scattering loss, because the traditional multi-angle reflector causes energy attenuation due to non-vertical incidence.

[0051] By superimposing the magnetic fields of the circular electrically controlled magnetic blocks 6, dynamic circular scanning of the electron beam is achieved with a static structure without the need for mechanical rotating parts. The circular path of the electron beam in the vacuum chamber avoids air scattering and energy loss caused by the non-vacuum environment of the traditional reflector. In addition, the magnetic field adjustment response speed is much higher than that of mechanical movement, and can match the crawler conveying speed in real time.

[0052] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the double-sided scraping module 13 includes an arc clamping block 131 that is slidably installed in the cavity of the annular irradiation chamber 5 through the embedded groove 10, and a T-shaped rubber plate 132 is fixedly installed on the arc clamping block 131. The first scraping coating 133 is fixedly installed on the end face of the T-shaped rubber plate 132 facing the annular titanium window 12, and the second scraping coating 134 is fixedly installed on the end face of the T-shaped rubber plate 132 facing the electric-controlled magnetic block 6. The arc clamping block 131 is slidably clamped in the embedded groove 10 and is fixedly installed with magnetic coatings 135 on both side end faces, and the magnetic coatings 135 are tightly attached to the side walls of the embedded groove 10.

[0053] Among them, the configured double-sided scraping module 13 is arranged as a whole in the inner cavity of the annular irradiation chamber 5, and is slidably installed through the embedded groove 10, and the arc clamping block 131 is slidably clamped on the end faces of both sides of the embedded groove 10. A magnetic coating 135 is fixedly installed to cooperate with the rotation of the corresponding linkage ring module 8 adsorbed on the outside and rotate in conjunction. During the rotation, the first scraping coating 133 and the second scraping coating 134 on both sides of the T-shaped rubber plate 132 are respectively scraped. The first scraping coating 133 on the end face of the side facing the annular titanium window 12 includes but is not limited to a diamond-like carbon coating. In actual operation, the coating is deposited on the end face through a magnetron sputtering process. While ensuring cleaning power, it can significantly reduce the risk of surface damage. The second scraping coating 134 for the end face of the electrically controlled magnetic block 6 includes but is not limited to a titanium nitride coating, which is non-magnetic and has low resistivity and can withstand the scratching of metal debris on the magnetic surface. Through the combined design of DLC coating and TiN coating, the double-sided scraping module 13 not only achieves efficient cleaning, but also solves the core problems of traditional solutions such as rapid coating wear, electrostatic interference and high contamination risks, ensuring the long-term stability of the irradiation device in batch processing.

[0054] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9As shown, the outside of the annular irradiation chamber 5 is also provided with a linkage annular module 8, and the linkage annular module 8 includes an annular chuck 81, and the annular chuck 81 is movably clamped to the outside of the annular irradiation chamber 5 through the embedded groove 10 protruding from the outer wall of the annular irradiation chamber 5, and a gear ring 82 is also fixedly installed on the outer edge of the annular ring on one side of the annular chuck 81, and a servo motor 7 is fixedly installed at a position near the gear ring 82 on the side of the electron accelerator 4 through a bracket, and a gear disk 9 is fixedly installed on the output end of the servo motor 7, which is flush with the gear ring 82 above and below, and the side of the gear disk 9 is meshed with the gear ring 82, and the inner wall of the annular chuck 81 is tightly attached to the outer surface of the embedded groove 10, and the inner wall of the annular chuck 81 is provided with a metal coating corresponding to the adsorption of the magnetic coating 135.

[0055] Among them, the configured linkage ring module 8 is driven and controlled by the servo motor 7. The configured servo motor 7 is a motor structure that can be servo-controlled in the prior art. The gear plate 9 at the output end of the servo motor 7 rotates to drive the meshing gear ring 82 to rotate synchronously. When the gear ring 82 rotates, the ring chuck 81 can be controlled to rotate 360 ​​degrees on the outer surface of the ring irradiation chamber 5. During the rotation of the ring irradiation chamber 5, on the one hand, the inner liquid storage module 14 can be controlled to cooperate with the cleaning module 15 to clean the ring titanium window 12 in real time. On the other hand, the double-sided scraping module 13 inside the ring irradiation chamber 5 can be driven to rotate synchronously through adsorption to ensure the synchronous cleaning of the inner cavity and the outer surface.

[0056] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, a liquid storage module 14 is also provided on the inner ring of the annular chuck 81, and the liquid storage module 14 includes a first cavity shell 141 fixedly mounted on the inner ring of the annular chuck 81, the side of the first cavity shell 141 facing the annular titanium window 12 is a planar structure, and the side away from the annular titanium window 12 is a semicircular convex bottom structure, a reset airbag sleeve 146 is fixedly mounted inside the first cavity shell 141, and a catheter passing through the first cavity shell 141 is fixedly mounted on the side end of the reset airbag sleeve 146, and a drainage catheter 83 is fixedly mounted at a position on the side of the first cavity shell 141 of the annular chuck 81, and the drainage catheter 83 is communicated with the catheter passing through the side end of the reset airbag sleeve 146, and a storage tank 84 is fixedly mounted on the outer end of the drainage catheter 83.

[0057] Among them, the configured reset airbag cover 146 is an airbag structure made of tough material in the prior art. When not under pressure, the whole is in an expanded state, and when under compression, it will shrink, and negative pressure can be generated during each contraction and expansion process, and the negative pressure is used to adsorb the reagent in the storage tank 84 outside the drainage catheter 83. The stored reagent is a mixed reagent of deionized water and a neutral surfactant. On the one hand, it does not chemically react with the titanium material, does not destroy the sealant between the annular titanium window 12 and the assembly frame 1, and has no residue as a whole, avoiding contamination of the vacuum chamber or interference with the electron beam path. On the other hand, it can effectively remove fruit and vegetable juice residues, dust and grease. One side of the first cavity shell 141 is a planar structure, and the other side is a semicircular convex bottom structure. On the one hand, it is to ensure that the plane of the cleaning module 15 is relatively flat, and on the other hand, it is to ensure that the reset airbag cover 146 can be subjected to more uniform force during the subsequent squeezing of the U-shaped extrusion plate 144 from top to bottom.

[0058] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the interior of the drainage catheter 83 is provided with a one-way valve, the top of the storage tank 84 is provided with a sealing cover, and the two side ends of the arc block 131 are movably installed at the position where the sliding ends are stuck in the embedded groove 10, and the side of the first cavity shell 141 facing the annular titanium window 12 is also provided with a cleaning module 15, and the cleaning module 15 includes a second cavity shell 151 fixedly installed on the plane structure of the first cavity shell 141, and the surface of the first cavity shell 141 is provided with a reserved opening 147 leading to the second cavity shell 151, and the side of the second cavity shell 151 facing the annular titanium window 12 is sealed with a sealing sleeve cover 153, and the surface of the sealing sleeve cover 153 is fixedly installed with a cleaning sponge 154, and the surface of the reset airbag sleeve 146 is connected to the delivery catheter 148, and the delivery catheter 148 leads to the cleaning sponge 154 through the reserved opening 147.

[0059] Among them, a one-way valve is configured inside the drainage catheter 83 so that liquid can pass through the drainage catheter 83 only during adsorption. During operation, the one-way valve is opened only when the reset airbag sleeve 146 is squeezed and reset, and the reagent in the outer storage tank 84 is transferred to the reset airbag sleeve 146. Similarly, a one-way valve is also installed in the delivery catheter 148 on the surface of the reset airbag sleeve 146. The one-way valve in this position can only discharge the reagent outward. During operation, the reagent can be discharged through the valve when the reset airbag sleeve 146 is squeezed, and the reagent is directed to the cleaning sponge 154, so that the cleaning sponge 154 is soaked with the reagent.

[0060] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, trigger U-shaped plates 142 are inserted and installed at both sides of the plane of the first cavity shell 141, and a U-shaped extrusion plate 144 is fixedly connected to one end of the trigger U-shaped plate 142 inserted into the cavity of the first cavity shell 141. The U-shaped extrusion plate 144 is integrally fitted on the reset airbag sleeve 146, and a ring disk 143 is movably installed in the U-shaped open end of the trigger U-shaped plate 142. The toothed ring 11 is fixedly installed at the two side ends of the inner ring edge of the annular irradiation cavity 5, and the reset rod 145 is fixedly installed at both side ends of the U-shaped extrusion plate 144. The ring disk 143 is engaged and stuck in the tooth of the toothed ring 11 under the reset force of the reset rod 145.

[0061] Among them, the configured trigger U-shaped plate 142 is movably installed at the two side positions of the plane end of the first cavity shell 141 through the reset rod 145, and the reset rod 145 is an elastic sleeve rod structure that can be reset in the prior art, which is used to ensure that the trigger U-shaped plate 142 is always in an outward protruding state, so that the annular disk 143 fits tightly in the tooth mouth of the tooth mouth ring 11, and as the annular chuck 81 rotates, the first cavity shell 141 configured on the annular chuck 81 will also rotate accordingly. During the rotation process, the annular disk 143, which fits tightly in the tooth mouth of the tooth mouth ring 11, will reciprocately squeeze the trigger U-shaped plate 142 along with the tooth mouth, causing the trigger U-shaped plate 142 to reciprocate up and down, controlling the U-shaped squeezing plate 144 on the trigger U-shaped plate 142 to reciprocately squeeze the reset airbag sleeve 146, so that the reset airbag sleeve 146 reciprocates to perform negative pressure adsorption and discharge.

[0062] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the cleaning module 15 also includes a spray plate 158 fixedly installed at the middle position of the surface of the sealing sleeve cover 153, and exhaust slots 157 are fixedly installed at the two side ends of the cleaning sponge 154. A plurality of liquid guide wires 155 are fixedly installed at the bottom of the cleaning sponge 154, and the liquid guide wires 155 extend to the inner top position of the second cavity shell 151.

[0063] Among them, the configured spray plate 158 is a cavity-plate structure, and a number of atomizing spray ports are opened on the outer surface of its cavity. The configured exhaust slot 157 is an air outlet structure with a protective net in the prior art. The configured liquid guide wire 155 is a capillary wire in the prior art. The material has high porosity and liquid affinity, and pump-free liquid transportation is achieved through capillary force.

[0064] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the cleaning module 15 also includes a partition plate 152 fixedly installed inside the second cavity shell 151, and the partition plate 152 symmetrically divides the second cavity shell 151 into two independent cavities, the upper cavity of the partition plate 152 is used to store the reagent adsorbed by the liquid supply wire 155, and the delivery conduit 148 is sealed through the partition plate 152 and connected to the spray plate 158, and the interface end connected to the spray plate 158 is equipped with an electric control valve.

[0065] The cavity on the partition plate 152 is used to store a reagent for adsorption by the liquid-leading wire 155 , wherein the reagent is deionized water, which is used to purify the cleaning sponge 154 during the subsequent cleaning process.

[0066] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, electrically controlled fans 156 are fixedly installed at both ends of the lower cavity of the partition plate 152 , and the output end of the electrically controlled fan 156 is connected to the exhaust slot 157 through a conduit. The spray plate 158 and the exhaust slot 157 are both recessed inside the cleaning sponge 154 .

[0067] Among them, the configured electric-controlled fan 156 is a fan structure capable of gas transportation in the prior art. It is internally configured with fan blades connected by silent gears and can rotate forward and backward. On the one hand, it can transport airflow to the exhaust slot 157 through the duct, and on the other hand, it can transport the heat generated by friction on the bonding end cleaning sponge 154 through the reserved opening 147 to the first cavity shell 141 through wind force, thereby reducing the heat at the bonding end on the one hand and increasing the temperature in the first cavity shell 141 on the other hand, heating the reagent in the negative pressure cavity to a certain temperature.

[0068] The specific cleaning principle of the configured cleaning module 15 is:

[0069] First, the fruits and vegetables to be processed in batches are conveyed by the conveyor belt 2 through the irradiation area of ​​the circular irradiation. During the irradiation process, the electron beam is accelerated by the electron accelerator 4, and the accelerated electron beam is added to the vacuum cavity of the circular irradiation chamber 5. The electron beam is controlled by the electric magnetic attraction of the outer electric magnetic attraction block 6 to be emitted in a circular shape onto the circular titanium window 12, and 360-degree circular irradiation is carried out in conjunction with the circular titanium window 12.

[0070] Then, during the maintenance work, the gear ring 82 is driven to rotate by the gear plate 9 at the output end of the servo motor 7, so that the annular chuck 81 rotates 360 degrees around the outside of the annular irradiation chamber 5. During the rotation, on the one hand, the double-sided scraping module 13 in the cavity of the annular irradiation chamber 5 is adsorbed by the adsorption of the annular chuck 81 to perform double-sided scraping. On the other hand, the liquid storage module 14 inside the annular chuck 81 rotates synchronously, so that the annular disk 143 on the trigger U-shaped plate 142 on both sides of the first cavity shell 141 reciprocates. The toothed ring 11 is squeezed to control the U-shaped squeezing plate 144 to reciprocate and squeeze the reset airbag sleeve 146. During the reset process of the reset airbag sleeve 146 cooperating with the reset rod 145, a contraction and expansion operation is completed to introduce the mixed reagent stored in the storage tank 84 into the delivery conduit 148. During maintenance, it is only necessary to open the electric control valve at the position of the spray plate 158 to soak the cleaning sponge 154 with the mixed cleaning reagent, and use the soaked cleaning sponge 154 to clean the outer surface of the annular titanium window 12 to ensure the stability of the electron beam emission.

[0071] Then, the electric control valve on one side of the spray plate 158 is closed, and the surface of the cleaning sponge 154 is purified twice by the liquid brought by the liquid lead wire 155, and the surface of the annular titanium window 12 is cleaned twice using the cleaning sponge 154 soaked in deionized water to further remove the residual reagents on the annular titanium window 12.

[0072] Finally, by turning on the electric-controlled fan 156, the airflow is directed to one end of the exhaust slot 157 through the blowing effect of the electric-controlled fan 156, and the surface of the annular titanium window 12 is subjected to secondary treatment by utilizing the characteristics of blowing and dry sweeping. After the online processing is completed, the conveyor belt 2 can be opened to continue the batch irradiation processing.

[0073] A method for using an irradiation-based batch fruit and vegetable processing device comprises the following steps:

[0074] S1: First, the conveyor belt 2 is started to transport the fruits and vegetables into the irradiation area. The electron accelerator 4 injects the electron beam into the vacuum cavity of the annular irradiation chamber 5. The electrically controlled magnetic block 6 deflects the electron beam along the annular path through the magnetic field, and the fruits and vegetables are irradiated 360 degrees through the annular titanium window 12.

[0075] S2: Then, the servo motor 7 is started to drive the gear plate 9 to drive the gear ring 82 to rotate, so that the annular chuck 81 of the linked annular module 8 rotates around the annular irradiation chamber 5. The annular chuck 81 absorbs the magnetic coating 135 of the double-sided scraping module 13 through the metal coating, driving it to slide along the embedded groove 10 and simultaneously clean the annular titanium window 12 and the end surface of the magnetic block 6;

[0076] S3: Then, when the annular chuck 81 rotates, the annular disc 143 of the U-shaped plate 142 is squeezed by the toothed ring 11, pushing the U-shaped squeezing plate 144 to compress and reset the airbag sleeve 146. The airbag contracts and draws the mixed reagent from the storage tank 84 through the drainage conduit 83. When it expands, it is transported to the spray plate 158 through the delivery conduit 148 to soak the cleaning sponge 154. The liquid drainage wire 155 absorbs the deionized water in the upper chamber of the partition plate 152 for secondary purification of the sponge.

[0077] S4: Finally, the electrically controlled fan 156 is started, and air is delivered to the exhaust slot 157 to sweep away the residue on the surface of the annular titanium window 12. At the same time, the friction heat is introduced into the first cavity shell 141 through the reserved opening 147. After the air flow accelerates the drying of the cleaning sponge 154, the spray valve is closed and the irradiation operation is resumed.
